Answer:
In this situation, the best command to switch the SELinux profile to permissive mode for Firefox would be:
`setenforce 0`
The `setenforce` command is used to temporarily change the enforcement mode of SELinux. Setting it to "0" switches it to permissive mode, where SELinux still logs policy violations but allows them to occur without blocking or denying them.
By using the `setenforce 0` command, you can troubleshoot the issue by temporarily disabling the SELinux enforcement for Firefox and observe if it resolves the problem. Remember that this change is temporary and only for troubleshooting purposes.
